STRIK-ING ATTACHMENT FOR TIMEPIECES.

Application area July 18, 1913.

To all w 7mm it may concern Fe it known that I, ()LAF Fl. Gisnr, citizen of the United States, and a residen of the city of New York, borough of Brook lvn, in the county of Kings and New York, have invented a new and Impro Jed Striking Attachment for Timepieces, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved striking attachment for watches and other timepieces, and arranged to strike the hours and half hours and to be driven from the main spring of the timepiece.

In order to accomplish the desired result use is made of an auxiliary motor spring, wound up from the main watch spring when the latter is running down, striking devices controlled by said auxiliary motor spring, an hour snail on the hour hand arbor of the timeplece, a spring-pressed main lever adapted to engage the said snail, and eriodically actuated locking and releasing devices for the said auxiliary motor spring and governed by the said main lever.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an enlarged face view of a watch provided with the striking attachment, parts of the cover, dial and hour hand being shown broken out; Fig. 2 is a similar view of the attachment. the cover, dial and hands of the watch being removed; Fig. 3 is a similar view of the driving gear for the auxiliary motor spring and the striking devices; Fig. is an edge view of the same with the bearings in section; Fig. 5 is a sectional side elevation of tlie striking attachment as applied, the section being on the line 5-5 of Fig. 1, with the cover and dial removed; Fig. 6 is a face view of the auxiliary spring and its barrel with the barrel cover removed; Fig. 7 is a sectional side elevation of the same; Fig. 8 is an enlarged cross section of the clutch mechanism for the driving pinion of the auxiliary motor spring; Fig. 9 is a face view of the locking and releasing device in hour strik} ing position; Fig. 10 is a similar view of the same in half hour striking position;

enlarged under side view of the end of the main lever provided with the springpressed arm for engagement with the hour pg ng and locking pawl; and Fig; 12 is an The striking attachment for the watch is 'lfpreferably mounted on the front face of the "frame A carrying the watch movement, the striking attachment being located directly under the dial B on. which indicate the hour and minute hands 13 and 13 On the hour hand arbor B is secured an hour snail G engaged by one end D of the main lever D fulcrumed at D on the frame A and pressed on by a sl'vring E. The end D is preferably in the form of an arm fulcrumed on the main lever D and pressed on by a spring D to allow turning of the hour arbor in either a forward or backward direction when setting the watch to correct time without danger of injuring the arm D by the snail C. The other end of the main lever D is provided with a rack D having ratchet teeth and an offsetshoulder D adjacent the innermost tooth of the rack D as plainly indicated in Figs. 1, 2, 9 and 10. The rack D and the shoulder D are adapted to be engaged by a locking and releasing pawl F fulcrumed at F on a bridge A attached to the frame A of the watch. The locking and releasing pawl F is provided with an arm F terminating in an angular lug F (see Figs. 5 and 11) adapted to engage a stop pin G attached to a gear wheel. G secured on a shaft G journaled in suitable bearings on the frame A and the bridge A (see Fig. 5). on the shaft G is secured a single tooth wheel H adapted to engage the teeth of the rack D to impart a step by step s vinging motion to the same and the main leverD, according to the number of hours to be struck, as hereinafter more fully explained, it being understood that the position of the lever D is governed by the end D on the snail C. A spring F presses the pawl F so as to hold the lug F normally in the path of the pin G to hold the gear wheel G and consequently the wheel H from rotating. The shaft G and the wheels G and H are adapted to be driven from an auxiliary spring motor I wound up from the main watch spring J of the watch during the time that the main watch spring J is running down, as hereinafter more fully explained. For the purpose men= tioned the shaft G is provided with a pinion Gr (see Figs. 3, 6t and 5) in mesh' with a gear wheel G secured on a shaft G journaled on the frame A and provided with a pinion G in mesh with a gear wheel I attached to or formed on the barrel I of the auxiliary spring motor I. The barrel 1 is mounted to rotate on a shaft 1 journaled on the frame A and the bridge A, and on the said shaft 1 is secured the inner end of a helical spring I connected at its outer end to the barrel 1 (see Figs. 6 and 7). A spring-pressed dog I engages the gear wheel I to hold the barrel 1 from rotating ,in the wrong direction during the winding of the spring. V

The spring barrel 1 is provided with a toothed striker wheel K adapted to engage a click K fulcrumed at K on the frame A and engaging a shoulder K on the fulcrum end of a striker K fulcrumed at K on the frame A. The hammer K of the striker K is adapted" to strike a ring K held suspended on the frame A to sound hours and half hours, as hereinafter more fully explained. The heel of the striker arm la is pressed on by a spring K so that when the click K is actuated from the striker wheel K the striker arm K is released to allow the spring K to swing the striker inward so that the hammer K strikes the ring K and sounds the same. It is understood that when the locking and releasing pawl r is swung from its normal position to the left then the lug F moves out of engagement with the stop pin G'to allow the spring I to rotate the barrel I in the direction of the arrow 03 so that the striker wheel K actuates the click K to release the striker K so that the hammer K strikes the ring K? and soundsthe same. It is understood that the click K imparts a return movement to the striker K while the spring K imparts a striking motion to the striker K to sound the ring K whenever the click K is actuated by the striker wheel K, as before explained;

It will be noticed that when the pin G is released by the lug F, as mentioned then the gear wheel I in rotating in the direction of the arrow a rotates the pinion G of the train of gear wheels G G and G to rotate the toothed wheel H and cause the lat ter to impart a step by step swinging motion made: On the shaft I is secured a gear wheel L in mesh with a gear wheel L fas' tened on a shaft L journaled in suitable hearings in the frame A and the'yoke A The gear wheel L is provided with a spring L adapted to engage a pin L held on the pinion L mounted to rotate loosely on the shaft L previously mentioned. The pinion On the upper end of the shaft L is secured a cam 0 having a long hour lug O and a short half hour lug O diametrically opposite the long hour lug O, as plainly indicated in Figs. 1, 2, 9 and 10. The lugs O and Q are adapted to engage the free end of releasing lever P fulcrumed at P and pressed on by a spring P so as to normally hold the free end of the lever P in tie path of the lugs O and 0 The lever P is adapted to engage the releasing'arm F on the pawl F so as to swing the said pawl F and the arm F to the left with a view to move the lug F out of the path of the pin G for releasing the striking device, as previously explained. On the under side of the releasing lever P is arranged a depending pin P adjacent the lug to engage the stop pin G immediately after the lug F has moved to the left out of engagement with the stop pin G. By this arrangement the stop pin G is held temporarily locked by the pin P until the long or the short lug O or O has passed the free end of the releasing lever P. When this takes place he lever P is swung back to the right by the action of the spring P to release the pin G and allow the gear wheel G to rotate.

. The operation is as follows: \Vhen the several parts of the striking attachment are in normal dormant positionthen the lug F is in the path of the pin G and consequently the striking attachment is held in inactive position with the pawl F in engagement with the shoulder D of the main lever D. 7 During the time the watch is running the auxiliary motor spring I is wound up and the cam O isrotating, and when the minute hand B reaches a twenty minutes past thehour position, the short half hour lug O has engaged and imparted aswingingmotion to the releasing lever P so as to swing the pawl F to the left, as previously explained, with a view to disengage the lug F from the pin G andto move the pin P into engagement with the said'pin G. At the same time the pawl F disengages the shoulder 1D to allow the main lever D'to swing downward until the first tooth of the rack D engages the free end of the pawl F to hold the latter against further downwardswinging movement; When the minute hand B reaches the half hour position and the lug-O finally passes the free end of the releasing lever P then'the latter swings to the right by the action of its spring P to release. the pin G' and to allow the auxiliary motor spring 1 to unwind whereby a rotary motion given to the striking wheel K and to the train of gear wheels G G and G. The striking wheel K now actuates the click K whereby the striker K is swung inward and v 1611 the corresponding tooth of the striker heel K has passed the c ick K then the spring K returns the str K to cause the hammer K to sound the ring K". The rotary motion given to the gear wheel G. causes the rotation of the si e tooth wheel H which now engages n D' and imparts an upward swing ing motion to the main l ver D so that the free end of the pawl F drops back into reengagement with the shoulder owing o the action of the spring F. hen this place the arm F has swung to the t a suticient distance to move its lug r" into the path of the pin G whereby the wheoi is stopped after having made one coniplet revolution.

.Vhen the minute hand B reaches a ten minu to the full hour position, the hour lug O has engaged and swung the releasing lever P to the left a sutllcient distance to swing the pawl F in a like direction until its free end clears the shoulder D of the rack D and allows the main lever D to swing downward until the first rack teeth abuts against the free end if the pawl F. During the movement of the pawl F to the left the lug F moves out of engagement with the pin G and the pin L 3 moves into engagement with the said pin G to hold the latter in locked position until th lug O has fully cleared the free end of the lever P, as hereinafter more fully explained. lVhen the minute hand B reaches a live minutes to the hour position the lug O has swung tie lever P a farther distance to the left to cause the pawl F to disengage the first tooth of the rack D to allow the main lever D to swingdownward by the action of its spring E until the arm D abuts against the snail C at a point corresponding to the next full hour. If the next full hour is say nine oclock the lever D swings down the distance of nine teeth the rack D When the minute hand reaches the full hour position the long lug G clears the free end of the lever P, and in doing so allows the lever P to swing to the right by the action of its spring P to unlock the pin G and to allow the wheel G to rotate, the said wheel G as well as the striker wheel K being now driven from the auxiliary spring motor I as before explained. The striker wheel K now actuates the click 1 which in turn actuates the striker l to cause the hammer K to strike the ring K nine times to indicate the corresponding hour, and at the same time the single tooth'wheel H imparts a step by step movement to the rack D to swing the lever D upward until scribed can be the free end of the pawl F drops back into engagement with the shoulder D When this takes place the lug F has return d into the path of the pin G to arrest the movement thereof and thus stop further action of the auxiliary motor spring I for the time being.

It is understood that when the main lever D is swung upward by the action of the rotating single tooth wheel ll engaging the rack D the free end of the pawl F drops successively into the corresponding teeth or" the rack D thus holding the lug F out of the path or" the pin G and allowing the wheel G to rotate until the free end of the pawl F reengages the shoulder It is also understood that when the single tooth wheel H lifts the rack D an upward swinging motion is given to the lever D to li the arm D out of engagement with the snail C. The above-described operation is repeated for each half hour and full hour, that is, when the minute hand nears the half hour position the lug imparts a swinging motion to the lover I, and when the minute hand B nears the full hour the lug (f engt ges the said lever P and actuates the same.

The striking attachment shown and dereadily applied to watches as now constructed with a few minor changes in the form of the frame or plate A.
